WASHING-MACHINE.

. Application filed May 14, 1919.

. fulllV-ashing-Machine, of which the following is a specification.

This invention relates to a washing machine, and particularly to a power driven machine adapted to be mounted in a pair of set-tubs of the usual type.

It is the general object of my invention to provide a machine of this type which i will be effective and satisfactory in use, and all parts of which may be stored substantially within the tubs when not in use, without dismantling the mechanism.

With this general object in view an important feature of my invention relates to a twopart rotatable washing cylinder and to a cover therefor, so constructed that the cover and the two parts of the cylinder may be nested together substantially within one of the tubs when not in use.

Another feature relates to the provision of motor driving mechanism for a washing machine, so designed and constructed that it may be disposed within an adjacent tub, in position for immediate use at any time. I also provide a wringer movable about a horizontal axis to and from operative position, the wringer being provided with the usual driving, stopping and reversing control.

My invention further relates to arrangements and combinations of parts which will be hereinafter described and more particularly pointed out in the appended claims.

A preferred form of myinvention is shown in the drawings, in which Figure 1 is a front elevation of my improved washing machine, part of the tub being broken away;

Referring to the drawings, my improved washmg machine oomprlses a cylinder formed of two substantially semi-cylindrical portions 20 and 21 one end of the inner port1on-20 being fixed to a driving shaft 22 and portion 21 being loosely mounted on said shaft. The outer portion 21 1s provided with a door 23 hinged thereto at 24 and held normally in closed osition by a catch or latch 25. A latc 26 on the cylinder portion 21 coiiperates with a stud 27 on the portion 20 to hold the parts in operative position, in which position they form a continuous perforated cylinder. The parts 28 and 29 (Fig. 13) fixed 1n the portion 20 extends longitudinally of the cylinder and are adapted to engage the clothes and cause movement thereof.

The driving shaft 22 is supported in a separable bearing 30 and the opposite ends of the cylinder and cover are supported on a shaft 31 rotatable in a separable bearing 32. The bearings 30 and 32 are supported on a base casing 33 adapted to fit loosely within a set-tub of the usual type, and formed as a water tight receptacle having plan view of the cylinder a drain opening 34: in its bottom side. End

braces 35 project below the casing 33 and support the casing in slightly raised position above the bottom of the set tub. An inlet opening 36 is provided in an off-set portion of the casing 33, and a handle 37 extends upward through the casing from a plug 38 adapted to close the drain opening.

One end of the cylinder is preferably given a somewhat conical shape to provlde increased capacity. A semi-cylindrical cover 39 is loosely mounted upon the shafts 22 and 31 as previously described and a latch 40 (Fig. i) is provided for holding the cover in raised position. When the washer is not in use the cover may be nested outside of the two portions of the cylinder, thus leaving all parts of the washersubstantially within the tubs and permitting a flat cover A wringer 43 of any usual type is mounted to turn about a horizontal axis upon clamping studs 44 and 45, by which it may be retained in the vertical position shown in Fig. 5. When the clamping studs 44 and 45 are loosened, the wringer may be swung downward to the inoperative position shown in Fig. 1.

The studs 44 and 45 are supported on arms, 46 extended outward from a frame work 47 (Fig. 4) fitted over the middle partition of the set tubs and held in osition thereon by set-screws 48. 'Bars 49 i 5) extend downward from the framewor 47 and support a base 50 upon which the driving motor 51 is mounted. The base 50 also rests upon an adjustable strut 50*. The motor 51 is connected by a worm 52 and worm-wheel 53 to a horizontal shaft 54, to which is secured a spur gear 55, a onetoothed pinion 56, and a bevel gear 57. The spur gear 55 engages a similar spur gear 58 upon a parallel shaft 59 and the gear 58 carries a bevel gear 60 connected through an idle bevel gear 61 to drive a third bevel gear 62. The gears 60 and 62 are loose on the shaft 59 and are each provided with a clutch face adapted to engage a slidable clutch collar 63 positioned by an arm 64 pivoted at 65 to a bracket 66 loosely mounted for convenience upon the shaft 54.

The outer end of an arm 68 connected with the arm 64, projects into a cam-slot 69 Fig. 6) in a disk 70 having projections 71 Fig. 7) upon its back side adapted for engagement with the one-toothed pinion 56-, which has the usual single stud tooth 72 and the segment locking ring 73. Continuous movement of the one-toothed pinion 56 will thus cause intermittent advance of the disk 70 and will alternately connect the clutch-collar 62 with the bevel gear 60 and with the bevel gear 63, which rotate in opposite directions.

The clutch-collar 63 is keyed on the shaft 59 which has a sprocket gear 74 (Fig. 5) secured to the end thereof and connected by a sprocket chain 75, with a second sprocket '7 6. The sprocket 76 is provided with clutch teeth upon one end of its hub and is loosel mounted upon a short shaft 77 (Fig. 4)

rotatable in bearings in the framework 47 and adapted to be connected by a clamp 78 to the driving shaft 22 of the washing 0 linder. A clutch collar-79 keyed to the s aft 77 maybe moved into or out of engagement with the clutch teeth on the sprocket 76 by means of a handle 80.

The driving connections above described provide means for rotating the washing cylinder a certain predetermined number of revolutions in one direction, and for then reversing the direction of rotation by the action of the cam slot 69 in the disk 70and rotatlng the cylinder for a'similar length of time in the opposite direction, the starting and stopping of the cylinder 2021 being under the control of the handle 80.

The bevel gear 57 (Fig. 4 previously described engages one part 0 a double evel pinion 81 which in turn engages a bevel gear 82 (Fig. 5) on the lower end of a vertical shaft section 83 rotatable in fixed bearings 84, and alined with a second vertical shaft section 85 rotatable in bearings 86. The shaft sections 83 and 85 are squared at their adjacent ends, and a collar 87 (Figs. 5 and 8) is mounted to slide on said squared p)ort1ons and to be held in raised osition y a spring stop or latch 88. Fart ier upward movement of the collar is limited by a stop 89. A bevel pinion 90 is mounted at the upper end of the shaft 85 and engages a pair of bevel pinions 91 and 92 loosely mounted upon the lower roller shaft 93. A clutch collar 94 is keyed on said shaft and may be caused to engage clutch teeth on the bevel pinion 91 or on the bevel pinion 92, as desired, by proper manipulation of a handle 95.

When the wringer is to be moved to its lower or inoperative position, the latch 88 is pressed in and the collar 87 is moved downward on the shaft section 83, thus disconnecting the shaft section 85, after which the clamping studs 44 and 45 may be loosened and the wringer may be folded downward to rest upon the top of the motor casing as shown in Fig. 1.

Obviously a suitable cover 96 (Fig. 4) may be fitted in the set-tubs over the driving mechanism to prevent clothes becoming entangled therein after passing through the wringer. The base casing 33 may be easily filled by a hose 97, as indicated in Fig. 1, and may be as readily emptied by raising gp e plagg 38 by means of the handle 37,

I-Faving thus described my invention it will be seen that I have devised a power driven washing and wringing machine which may be conveniently supported and operated in the usual set tubs and which is so constructed that all parts may be stored substantially within the tubs when the machine is not in use.

Having thus described my invention it will be evident that changes and modifications can be made therein by those skilled in the art without departing from the spirit and scope thereof as set forth in the claims, and I do not wish to be otherwise limited to the details herein disclosed, but What I- claim is 1. In a washing machine, a rotatable washing cylinder comprising two semi-cy- -.1Ylindrical members having semicircular closed ends, and means to support and rotate said cylinder, one of said members being movable about the axis of the cylinder to a position inside of, the other member when the machine is not in use.

2. In a washing machine, a rotatable washing cylinder formed in two semi-cy lindrical .parts having semi-circular closed when the machine is not in use.
